THOMAS CRANEY, OF BAY CITY, MICHIGAN.
STEAM-G EN ERATO R.
SPECIFICATION forming part of Letters Patent No. 542,015, dated July 2, 1895.
Application filed April 11, 1895. $erial No. (N l- To all whom it may concern:
Be it known that I, THOMAS CRANEY, a citizen of the United States, residing at Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Steam-Generators, of which the following is a specification, reference being had therein to the accompanying drawings.
The invention consists in the construction of asteam-ge'nerator, andparticularly in the arrangement of the boiler-shell, the dues for the heated products of combustion, and a series of tubes through the boiler, whereby the products of combustion pass successively therethrough in different directions.
The invention further consists in the construction, arrangement, and combination of the various parts, all as morefully hereinafter described. V In the drawings, Figure 1 is a front elevation of my improved steam-generator.- Fig. 2 is a side elevation thereof. Fig. 3 is a vertical longitudinal section therethrough on line a? a), Fig. 4. Fig. 4 is a cross-section on line y y, Fig. 3, and Fig. 5 is a horizontal section on line .2 2, Fig. 3.
A is a horizontal boiler having the furnacetubes B extending horizontally therethrough near the bottom, in which are supported the grates C, the furnace-fines being provided with suitable fuel and ash doors, as shown.
' The rear end of the boiler I preferably inclose with a wall D, forming at the end of the boiler the vertical smoke-chamber E.
F is aseries of tubes extending longitudinally through the boiler, communicating at their rear ends with the smoke-chamber E and at their front ends with a smoke-chamber G, formed within thejacket H. At one side the chamber G connects with the longitudinal side smoke-chamber I, formed within the jacket J.
L is a series of tubes extending transversely through the boiler between the longitudinal series and connecting the side chambers I with the side chamber M, formed Within the jacket N on the opposite side of the boiler. This chamber at its top is provided with the smoke-escape pipe or stack 0.
Between the furnace-tubes and below the same is an air-tube P, extending from end t'o end of the boiler and which may be closed at the ends and be used simply as a dead-air tube, to lessen the water-space in the lower side chamber I, through the tubes L, into the opposite side chamber M, and thence out through the stack 0. Thus it will be seen that the heat passes twice longitudinally through the boiler across both ends and once transversely therethrough and across both sides. This construction greatly increases the heatingsurface of the boiler, and thus enables me to greatly decrease the size of boiler for a given horse-power and to economize in fuel over other constructions.
It will be seen by an inspection of Figs. 1 and 2 that I form a jacket around the middle of the boiler, being so divided and connected into the chambers described as to produce the circulation of the heated products of combustion.
It will be seen that the tubes stay the shell in both directions, and while other transverse stays, such as B, may be used, they are not I nace flue therethrough, the furnaces therein,
the rear end chamber, into which the furnace flue connects,the longitudinal tubes through the boiler connecting the rear chamber with the front, a front chamber, side chambers, with one of which the front chamber connects, and a series of transverse tubes connecting the side chambers, substantially as described.
3. In a boiler, the combination of the combustion chamber therein, the smoke chamber With which said first chamber communicates,
a series of tubes or lines above the co'mbus-' tion chamber, connecting the smoke chamber with a third chamber, a fourth chamber communicating with said third chamber, and a second series of tubes leading from the last chamber to the smoke stack, substantially as described.
4. In a steam generator, the combination with the horizontal boiler, of the combustion chambers therein, the smoke chamber at one end of the boiler, the jacket around the middle of the boiler and forming chambers on the other three sides thereon, and independent flues connecting the chambers on opposite sides of the boiler, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
THOMAS CRANEY. Witnesses:
M. B. ODOGHERTY, O. F. BARTHEL.
